A sheet metal operator is told that her standard is 1.875 hours per 100 units. If her wage is $16 per hour and she makes 800 units in 12 hours, what are her earnings? If the actual time is 16 hours, what is her guaranteed pay and efficiency for the 100% plan? A round shaft 6.5 in. OD has a specified length of 31.675 in. The facing dimension necessary for a smooth end finish is 1/16 in. The width of the lathe cutoff tool is 3/16 in. The length of the raw bar stock is 12 ft. The lathe collets requires a minimum of 4 in. for gripping the last part. The material costs $0.95/lb and has a density of 0.29 lb/in3. Determine the number of pieces that can be removed from the raw bar. What is the unit cost for the raw material? What is the value of material that is lost to waste, given that waste material has a salvage value of 10% of the original value? Find the shape yield
